“SHARE is not an acronym; it’s what we do.”

Blog Post created by Hu Yoshida Employee on Feb 28, 2017


I began my career in IT during the mainframe days. Now 40 years later, the mainframe and I are still around. Next week SHARE, the volunteer-run user group for IBM mainframe computers, will be holding its annual conference at the San Jose Convention Center, March 5-10. SHARE was founded in 1955 and is a forum for exchanging technical information about IBM mainframe systems. A major resource of SHARE from the beginning was the SHARE library. Originally, IBM distributed its operating systems in source form and systems programmers commonly made small local additions or modifications and exchanged them with other users. The SHARE library and the process of distributed development it fostered was one of the origins of open source software. If you ask the SHARE organization what the capital letters stand for they will tell you: “SHARE is not an acronym; it’s what we do.”


Hitachi Data Systems will be a Gold sponsor for this year’s SHARE conference and will be exhibiting in booth #308. Hitachi is featuring enterprise class, high-speed flash storage available in a variety of configurations to support mainframe performance and availability requirements. Mainframes still drive many high performance, core applications for Financial, telco, and other critical infrastructure verticals. For instance, at the 50th anniversary celebration of the IBM mainframe in 2014, Citibank CEO Walter Winston estimated that his company’s IBM z Systems could process about 150,000 transactions per second or nearly nine million transactions per minute. That type of performance needs a high performance, highly reliable and resilient storage system.


In order to support mainframes, the storage system must be able to support FICON channels, and all the storage management and business continuity features of modern mainframe systems. This eliminates all the new flash array vendors, except for our VSP F1500. Our new VSP G1500 hybrid array and all-flash VSP F1500 deliver increased mainframe performance with the industry’s only 100% data availability guarantee and powerful replication technologies to eliminate downtime. The following link, Mainframe Storage Compatibility and Innovation With

Hitachi Virtual Storage Platform G1x00 and F1500 , shows how we are not only compatible with IBM mainframe storage features, but also how we innovate through the development and testing of unique Hitachi storage and storage management features to provide mainframe customers with additional capability and value.


For instance, while Hitachi offers SSDs in these products, Hitachi offers its own flash modules (FMDs) that include onboard ASICs and data management intelligence to provide superior performance over SSDs. FMDs provide tighter management and wear information with the storage subsystem enabling us to extend flash life and provide predictable failure management. With scalability of up to 8PB of flash storage, 14TB FMDs, 2TB of cache, HDS gives you superior scaling of performance to meet changing data center needs. Our fault tolerant system architecture combined with powerful synchronous and asynchronous replication technologies enable multi-site business continuity to meet zero recovery point and zero recovery time objectives. Capacity is optimized with dynamic tiering, compression, and deduplication and security is provided with encryption of data at rest and Key Management Interoperability Protocol (KMIP). Just as important, the Hitachi FMD enables shredding of flash cells, even those that are not seen by the controller, and provides a report of the status of shredded cell for auditing purposes.
